WATER-CLOSET TANK.

SPECIFICATION forming part of Letters Patent No. 679,299, dated July 30,1901.

Application filed July l0, 1900. Serial No. 23,103. (No model.)

To @ZZ whom, it may concern:

Beit known that we, WILLIAM S. COOPER, Jr., a citizen of the United States, and JOHN DORRICOTT, a subject of the Queen of Great Britain, both residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Water-Closet Tanks, which improvement is fully set forth in the following specification and accompanying drawings.

Our invention consists of an improved construction of a water-closet tank whereinthe flow and supply of the water thereto may be 4regulated by simple and novel mechanism which can be easily actuated and is Anot liable to get out of order, all as will be hereinafter fully set forth, and particularly pointed out in the claims.

Figure 1 represents a sectional view of a Water-closet tank embodying our invention, certain portions of the apparatus being shown in elevation. Fig. 2 represents a side elevation of another embodiment of the principle of our invention. Fig. 3 represents a plan View of a portion of the actuating mechanism seen in Fig. 1, to be hereinafter referred to.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, 1 designates a tank, to the bottom 2 of which is secured the frame 3, the latter having the outlet 4, which may project through said base and is provided with the upwardly-extending wall or fiange 5, which serves as a valve-seat and is adapted to coact with the washer 6, which latter is held in position by means of the flange 7 of the nut 3, whereby said Washer isheld in contact with the flange 9 of the plunger 10.

11 designates a spider located within said plunger and provided with the opening l2, through which passes the stein 13, the latter being secured to any fixed point, as 14, wherefrom it will be seen that the plunger and the pipe 15, connected therewith, and their adj uncts will always move in a vertical line, and the valve will be properly guided, seated, and unseated under all conditions. The pipe 15 has pivotally connected with the upper portion thereof the lever 16, which is fulcrumed 5o at the point 17, the free end 18 of said lever having the cord connection 19 attached thered to, whereby the lever is actuated as desired.

2O designates a post or standard upon which is pivotally supported a lever 2l, having the bridges 22 and having integral therewith or secured thereto the arm 23, from which pro jects the rod 24, which carries a float 25.

26 designates a rod depending from the pin or other connection with the lever 21 and having attached to the lower portion thereof the valve 27, which is adapted to rest upon its seat 28, whereby a closure is formed for the passage 29, which leads to the main out let 4.

30 designates a latch which is pivotally mounted on the lever 21, the nose 31 of said latch hanging so that it is adapted to engage the shoulder 32 of the plunger 10 at the proper intervals, as Will be hereinafter explained.

In Fig. 2 we have shown another embodiment ofthe principle of our invention, wherein the lever 21 is replaced by a frame or cast ing 33, which is pivotally supported and has attached to one end thereof the rod 34, which actuates the valve 35, and instead of the dependent latch 30 we employ the dog 36, whose nose 37 is adapted to engage the shoulder 32 of the plunger 10, as already described, it being understood that in this figure we have shown the plunger 10 in elevated position.

The operation is as follows: The parts be-V ing in the position seen in full lines in Fig. 1 and the cord or connection 19 being pulled, the end 18 of the lever 16 is depressed, the opposite end being elevated and carrying with it the pipe 15, the plunger 10, and the washer 6, together With the other adj uncts. The water in the tank l is now permitted to flow through the opening 4, it being noticed that as the plunger 10 is elevated the curved face thereof strikes the curved face of the nose 3l of the latch 30 and pushes the same aside until the plunger 10 is above the nose, when the latter will engage the lower edge or shoulder 32 of the plunger and hold the same in elevated position, as seen in dotted lines, Fig. 1. As the water in the tank 1 descends the float 25 will be carried down, and as the lever 21 is connected with said float 25 by the arms 23 and 24 the said lever will be depressed,

IOO

. means for opening said valve, another means the passage 29 into the outlet 4 and from thence into the bowl, this constituting the afterow, the said valve 27 being reseated as the water from the supply which enters through the opening 38 reiills the tank l and raises the float 25, so that the parts assume their normal position, it being understoodf that suitable connection is made with the water-supply and with the bowl, so that these parts are operated at the proper time. The

same operation is applicable to the construction shown in Fig. 2, the dog 36 and the nose 37 acting in the same capacity and in the same manner as the latch 30. it will be noticed that the reseating of the plunger lO is in a slow manner as vit falls with i the water and is not released until near the valve-seat, whereby the closing will be quiet and comparatively noiseless.

limited in every instance as tothe exact construction.

- Having thus described our invention, what we claim as new, and ldesire to secure by Letters Patent, is-

1. In a device of the character named, a tank having an outlet, a valve therefor, one

2. In a device of the character named, a valve, means for raising the same, a latch adapted to hold the same in elevated position and a iioat suitably connected with said latch, l said float, latch and valve being adapted to l descend as the water in the ltank falls and with said lever Aand adapted to lower saidj valve as the water descends, and a second;

valve suitably connected with`said lever, whereby the same will be operated when the Iirst-mentioned valve is closed.

By this method thereto, valves for said passages, one of which serves as a flush-valve and the other as an afterflush-valve, a single iioat for actuating both of said valves, said iioat being adapted to fall as the Water in the tank descends and carry with it the Hush-valve which is reseated slowly and quietly and said iioat being adapted to open the afterflush-valve and then close the same as the Water rises in the tank.

5. In a device of the character named, a valve, means for raising the same, a latch adapted to engage with and hold said valve in elevated position, a pivoted lever to which said latch is movably secured and a iioat which is connected with said lever, whereby when said float falls with the water, it will depress said lever and carry with it said latch, which carries with it the valve which thus falls slowly as the water descends in the tank.
